Measuring the Angle of Refraction in a Triangular Prism Lab

Click For Summary
SUMMARY

The discussion centers on a lab experiment involving a triangular prism where participants measured the angle of incidence and angle of refraction to determine the index of refraction. The formula used for calculating the index of refraction is n = sin(angle of incidence) / sin(angle of refraction). Participants were instructed to calculate the index of refraction for multiple sets of angles to verify measurement accuracy. The process emphasizes the importance of consistency in results across different angle measurements.

I did a lab in school where I took a triangular prism and shined light though it. I measured the angle of incidence and angle of refraction for three different angles. The lab question first told me to find the index of refraction of the prism using the two angles. That was easy. The next question asked: “Using the two pairs of angles for the triangle, calculate the index of refraction for the prism for each set of angles.” I don’t know what I’m supposed to calculate here.

Nevermind. I figured it out.
 


Based on the information provided, it seems like you have already successfully completed the first part of the lab by finding the index of refraction for the prism using the angle of incidence and angle of refraction. The second question is asking you to calculate the index of refraction for the prism using the two pairs of angles that you measured. This means you will need to use the formula for calculating index of refraction, which is n = sin(angle of incidence) / sin(angle of refraction). You will need to do this calculation for each set of angles that you measured and compare the results to see if they are consistent. This will help to verify the accuracy of your measurements and the index of refraction that you initially calculated.
